Update:

Recently some very awsome cookiecutter-designs started to show up on thingiverse (like the escher cookie cutter or the jigsaw cookie cutter, and many more)
(and one of the local radiostations has played "last cristmas", because it's only 6 months till x-mas O_o )

So i thought about how the generation of such custom cookie cutters could be simplified and i developed a custom cookie cutter
generator in processing.
